RICHARD VOSE, OF NEW YORK, N. Y.

CAR-SPRING.

SPECIFICATION forming part of Letters Patent No. 330,446, dated November17, 1885.

Application filed May 23, 1885. Serial No. 166,439.

To @ZZ whom it may concern:

Be it known that I, RICHARD VosE, of the city of New York, county andState of New York, am the inventor of an Improvement in Oar-Springs, ofwhich the following is a specication, reference being had to the drawingaccompanying the same, and made a part thereof, in which the gure isasectional side view of one form of my spring when all steel spirals areused.

My invention consists in the combination of end conical spiral springswith a central cylindrical metal spring used as a cushion between saidend spiral springs.

In the drawings, Aand B are two conicallyshaped spiral springs, theapices of which are at the upper and lower ends of the spring. C and Care ilanged-lip bearing-cups, and D is a cylindrical spring placedbetween the two conically-shaped spiral springs, the bases of saidconical spirals resting on the flanges of' d d of C and C. If deemednecessary and desired, angcs d d may have inside lips; but these may bedispensed with. The projecting flanges g g', projecting into the basesof the springs A and B, prevent the cups or holders from any lateralmotion. G and G are end caps or' pieces commonly used in this class of(No model.)

combined spiral springs. It will now be seen that weight placed upon thetop of cap G first causes the spring A to act. This spring resting inflange d of cup C presses the same down onto the cylindrical centerspring, D. Spring D is then pressed down onto flange d of cup C', andmade to bear upon and press down the conical spiral B, and thus theentire spring is brought into action.

Vliat I claim, and desire to secure by Letters Patent, is-

1. A car-spring composed of two conical spiralsprings, in combinationwith a cylindrical spring placed between the two, substantially asdescribed, and for the purpose specified.

2. A car-spring composed of two conicallyshaped spiral springs, thebases of which rest on a holder which rests on a central cylindricalspring, said cups holding said spirals in position, substantially asdescribed, and for the purpose specified.
